have invented new improvements in line locks and' tabulating devices. In the preferred construction both. the line lock and tabulating devices are operated with the same actuator.

The invention is illustrated in the accompanying drawings as follows:

Figure 1 shows a section on the line 11 in Fig. 2. Fig.2, a vertical section, the section being taken in front of the universal bar. Fig. 3 a rear view of the machine. Fig. 4', a section on the line 44 in Fig. 5, showing details of construction of the dog mechanism of the line lock and tabulating devices. Fig. 5 is a section on the line 5-5 in Fig. 4. Fig. 6 is a section through the adjustable stop of the line lock. r

1 marks the frame as a whole; '2 the sides of theframe; 3 the rear cross bar of the frame; 4 a plate or platform extending toward the front of the machine from the cross bar 3; and 5 a downwardly extending lip or flange at the front of-the plate 4.

Smarksthe carriage which may beof any desired construction. The rails 7 are secured to the frame in any desired manner. These rails have the grooves 8 therein (see Fi 1). The carriage also has a rail 9 formed wit the grooves 10 therein and the rollers 11 are arranged in the grooves 8 and 10, forming a roller bearing for the carriage. A platen 12 is arranged in the-carriage and is provided with the usual paper feeding mechanism. A rack plate 13 is secured to the plate. 14 which is supported by the bars 7. The rack graduated, as tocorrespond to the spacing th rack lplate 13. This stop is shown in detail in ig. 6., It is provided with a verties perforation 17 in which arranged a of Armstrongv and.

plate is provided with the teeth 15 so The stop 16 is arranged on.

pin 18. A lower portion 19 of the in is of reduced diameter, forming a shou der 20. The erforation 17 does not extend in its full iameter uite through the stop 16, but forms a shoulder 21 near the bottom of the stop. A spring 22 is arranged around the reduced portion 19., resting on the shoulder 21 and against the shoulder 20. has the perforation 23 and the stop has a transverse slot 24- extending through the bottom of it of a depth sufficient to permit a pin 25 arrangedin the perforation 23 to en-'- gage theserrations 15 on the rack bar. B pushing down on the pin 18 the pin 25 is moved out of the notches in the rack bar so as to release the sto The stop may then ,be moved to any by permittingjthe pin to reenter one of the notches of the rack bar. p

.A plate 26 is secured to the bar 9 of the carriage by means of screws 27. It is provided with a notch 28 extending upwardly from the bottom of the plate and a lever 29 is pivoted The pin 18'- desired position and locked I on the screw 30. The screw 30 extendsinto the bar 9. than the dog 29 so that the d0 29 may swing in the notch. (See Figs. 4 am 5). A spring 30 tends to hold the dog 29 toward the rightas viewed in Fig. 4. An pivoted on the plate .26. normally in the osition shown in Fig. 4 by a spring 31*. A dbg lug 32 is arranged on, the side of the dog 29 in the path of a stop lug 33 which is carried by a swinging latch 34 on the stop 16. The latch 34 has a protruding finger 35 which extends into the path of a bail auxiliary dog 31 is 36. The. bail 36 is carried by the levers 37.-

The levers 37 are pivoted at 38 on the sides of the machine.

A link 39 extends from the The notch 28 is somewhat wider f It is maintained I lever 37 to a rock lever 40. The rock lever 7 40 is fixed on a shaft 41 extending from the .front toward the rear of the machine. The rod 41 is journaled on the lugs 42 and 43 extending from the side frame 2. A rock lever 44 is secured to the rod 41 and its up er end is engaged by and preferably pivotally connectedto a push pin 45. The push pin 45 on the side of the extends through a face 46 machine. An arm 47 extends from the rock lever 44 below the rod 41 and extends into a spring socket 48, which is arranged to yieldingly press the arm 47 inwardly on the rock arm 44 outwardly.

-' n will be noted that wheii the latch lug 3s is in contact with the dog lug 32 as shown in Fig. 4, a further movement of the carriage is blocked by this engagement. The 'feeding spring of the carriage, however, is sufliciently strong to carry the dog 29 to the left against, the tension of the spring 30. It has also carried the rack bar on which the stop'16 is mounted toward the right a distance of one half space, the effect of which will be hereafter described. When the line lock reaches the position shown in Fig. 4, and it is desired to release it for further operationthe pin 45 is pushed in carrying with it the rock arm 44 turning the rod 41 and swinging the arm 40 upwardly. This pushes up the link 39 and lifts the bail 36. The bail 36 contacting the finger 35 lifts the latch 34 so as to move the latch lug 33 above the 'path of the do lug 32.

This movement, however; brings the latch lug 33 into the path of the end of the auxiliary dog 31 so that a further movementpf the carriage is prevented. While in this position the dog 29 acting under the influence of the spring 3O swingst'oward the right, the dog lug 32 passing under the latch lug 33. Upon the release of the push pin, the bail drops down to its normal position allowing the latch 34 to drop down so as to clear the auxiliary do 31. The pivotal arrangement of the auxi iary dog permits the return of the carriage past the latch lug 33, even though the latch lug may be in the elevated position through manipulation of the push pin. The beveled edge at the left of the dog ug 32 also provides for the clearin of the latch lug on the return movement t e latch lug riding up this beveled surface so as to prevent locking.

The rack bar as before stated, has endwise movement. To accomplish this it is provided with the slots 49 which are of sufficient length to allow a movement of one half a space on the screws 49', thesaid screws extending through said slots and acting to secure the rack. The rack is held in normal position by the s ring 49*.

A rock lever 50 is preferably secured to the rack plate 13. This is pivoted on theshaft- 51 extending from front to rear of theoperating mechamsm, the shaft being secured to a post 51 extending upwardly from the cross plate 4. A link 52 extends from the op osite end of the rock lever from that secure to filate ,and is preferably. connected the rack with a be crank lever 53. The lever 53' is pivotally mounted on a stud 54 extendin downwardly from the plate 4. The bel crank lever has the slots 55 at its lower end which engage a rod 56 extending between the swinging arms 57, the rod being fixed on the said arms and maintaining them in parallel relation. The arms are ivotall mounted on the lugs '58 extending orwardf from'the lip '5; the arms 57 having the ots 59 arranged in their front edges and in position to engage a rod 60 extending across the machine from side to side, it being secured to the lever 61, and the lever 61 carrying the universal bar 62.

and a link 72 extends from this head to the universal bar and is connected with they universal bar by a pivotal oint 73. It will readily be seen that as the universal bar is depressed the rod is moved forward through the actionof the lever or link'7 2 on the head 71. A dog 74;is fixed on the rod 70 and is in position when the rod is pushed back to engage the ratchet teeth on the ratchet wheel 68. A second dog 75 is carried by the sleeve 7 5 the sleeve being slidingly mounted on the rod 70. The dog 75 islocked against ro- "tation on the rod 7 0 by a pin 76 and it is so spaced with relation to the dog 74 as to permit the dog 74 to clear the teeth on the forward movement of'the rod 70, allowing the ratchet wheel to move one half space and the dog 75 will clear the tooth just disengaged on the forward movement of the rod 70, allowing a second movement of the ratchet wheel one half s ace.'

When t e dog 29 engages the sto 16, it

moves the rack plate 13 edgewise a istance of one half space, that is the space which the forward movement of the rods 70 permit. This movement of the rack plate 13 one half space, acting throu h the bell crank lever 50,

hnk- 52, bell crank ever 53 upon the arm 57 swings the arm 57 so as to bring the'notch 59 on to the rod 60, thus locking the universal bar and locking the. machine. leasing movement incident to the lifting of the bail 36 heretofore described, no forward movement of the carriage is permitted because the auxiliary dog 31 engages the lug 33.- When, however, the bail resumes its normal position allowing the latch 34 to drop,

the other one half/space is com let'ed bringing the dog 75 in position on t e ratchet. The releasing mechanism which operates Upon the rewith the tabulator is as follows: A lever 76 is pivotally connected at 77 with the sleeve 7 5. t swingsfrom a stud 78 arranged on the bottom of the plate 4. This lever also passes into a spring socket7 9 so that it is normally kept in its forward position. A link 80 connects the lever 7 6 with a rock arm 81. The rock arm is fixed on the shaft 82. Rock arms 83 extend rearwardly from the rock. shaft 82 and are connected with the releasing 1 bar 92 so that the extension is raised with the 7 extension does not necessarily lift t e tabudiate mechanism formed by the rock arms bail 84. -An extension 85 is-fixed on the upper end of the releasing bail and has aslot 86 near its upper end. This slot en ages a rod 87 which extends lengthwise of t e carriage and is at all times in engagement with the slot. The rod 87'is fixed on the rock arms 88 so that it is maintained in parallel relation. The rod 86 is connected with a release lever 89 mounted on avpin 89' on the carriage, which operates as a bell crank lever on the rod 87 to lift the same. The movement of the rod carries with it the extension 85, bail 84 and the bail acting through the interme- 83, shaft 82,. arm 81, link and lever 70, moves the sleeve 75 toward the-rear and this carries the dog 75 out of the path of the teeth of the ratchet wheel 68, thus releasing the carriage. The extension is provided with a rearwardl extending hook 90 which extends over a finger 91 on theqtabu-lating tabulatingbar, although the raisin of the lating bar.

The tabulating bar 92 extends across the rear of the machine and is fixed on the lever 37 and oscillates with these levers and with the bail 36. It has a series of notches 93 one preferably for each space of the ma-v chine and the U shaped stop plates 94 are secured, inthese notches. *"They may be shifted. at pleasure so as to give the desired tabnlating stops. The stops 94 are so ar' ranged that when the lever 37 and bail 36 are raised it carries the stops 94 into the, path of the dog 29 so that the carriage will be stopped through the engagement of the dog w1th the stop. This lifting of the stops into the path of the. dog, however, releases the carriage so that no matter where the carriage may be, the lifting of the tabulator bar releases the carriage and permits it to move to the next tabulating stop. The release of the push pin allows the tabulator barto return to normal position permitting the normal operation of the machine until the next tabulating stop is desired when another operation of the push pin operates the release mechanism and brings another stop into the path of the dog 29.

It will be noted that the same actuator, that is the push pin, operates both the tabulator and the line look. It will also be noted that .the same dog 29 is engaged by the line lock stop and the tabulator stops. It will? also be noted that the member carried by the levers 37 releases the line lock stops and actuates the tabulator stops. What I claim as new is:
